I bought a Digital Multimeter from a retailer and they won't let me return it. I used it only a couple of time and have had it laying around since then. Right from day one the knob was very hard to turn. Then all of a sudden it now spins freely. It still works but the the knob spins without the clicks to index it on a setting. Meaning it can very easily move from one setting to another by itself. What can I do. I feel like I bought a defective unit and the retailer won't take it back. I lost faith in this brand of multimeter but feel like I have been ripped off because as a consumer I can't even return it for a refund even though it is defective.

That's a bit past our 30-day return/replace period, so it's reasonable for them to send you here for more information. Let them know we've approved store credit for the cost of that meter, to be applied to the cost of another one.

They can contact our business team by sending a link to this page to support@adafruit.com and our business team with settle up through their account with us.
